Problems solved by technology

Therefore, for mobile phone casings, car interiors, etc., without proper waterproof protection, electronic equipment often suffers from short circuits, performance degradation, and rust, making it difficult to operate at high speed and reliably for a long time
[0004] In the existing solution-type waterproof coating technology, acrylate, epoxy resin, polyurethane, etc. are often used as waterproof treatment for electronic components, which have high viscosity, difficult coating, and relatively thick coating, which will not meet the requirements of electronic components. Equipment is becoming more and more sophisticated, and the demand for miniaturization
At the same time, although the fluorine-containing coatings that have been reported so far can achieve relatively good hydrophobic coatings, they cannot meet the high-level waterproof requirements due to the thin coatings.

Abstract

The invention discloses a novel wear-resistant waterproof electronic material coating and a preparation method thereof. The invention provides a UV-cured waterproof wear-resistant coating composition.The UV-cured waterproof wear-resistant coating composition comprises fluorine-containing acrylate, an acrylate monomer, a urethane acrylate oligomer and wear-resistant nanoparticles. Besides the hydrophobic and waterproof properties of the fluorine-containing coating, the coating has the properties of a wear-resistant hard coating. The invention provides a wear-resistant waterproof coating for electronic products.

Description

Technical field: [0001] The invention relates to a UV curing waterproof and wear-resistant coating composition, which comprises fluorine-containing acrylate, acrylate monomer, polyurethane acrylate oligomer and wear-resistant nano particles. The invention not only has the hydrophobic and waterproof performance of the fluorine-containing coating, but also has the performance of a wear-resistant hard coating, and provides wear-resistant and waterproof coatings for electronic products. [0002] technical background: [0003] With the rapid development of electronic technology, various electronic products, such as computers, tablets, portable e-books, earphones, etc., will malfunction after being wet with water. Therefore, for mobile phone casings, car interiors, etc., without proper waterproof protection, electronic equipment often suffers from short circuits, performance degradation, and rust, making it difficult to operate at high speed and reliably for a long time.
